Indication of Interest (IOI)

An indication of interest is a nonbinding expression of potential demand for a security, offering, trade, or investment opportunity.

An Indication of Interest (IOI) is a term utilized in the underwriting process to denote a conditional, non-binding interest in purchasing a security that is currently in registration. It represents a preliminary expression by a potential investor indicating they are interested in purchasing shares in the upcoming issuance, but it does not constitute a firm commitment to buy.

Functionality of Indication of Interest

The IOI serves several purposes within the financial markets, particularly in the context of Initial Public Offerings (IPOs) and other public offerings of securities.

Role in Underwriting

Underwriters collect IOIs from institutional and retail investors to gauge the level of demand for the upcoming securities. This information helps underwriters determine the final offer price and allocation of shares.

  • Price Discovery: By aggregating IOIs, underwriters can set a more accurate and market-reflective price for the securities.
  • Allocation Strategy: IOIs assist in forming a strategy for how shares will be allocated among various investors to ensure broad distribution and stable trading post-issuance.

Example of Indication of Interest

To illustrate, consider a tech company planning an IPO. During the pre-IPO roadshow, the company and its underwriters collect IOIs from investors. An institutional investor might submit an IOI for 100,000 shares at a price range of $20-25 per share. This indicates their interest without binding them to purchase the shares.

Applicability

  • Regulatory Compliance: IOIs need to comply with specific regulatory requirements to ensure transparency and fairness in the IPO process.
  • Market Sentiment: IOIs are also indicative of market sentiment, offering insights into how an offering is perceived before it hits the market.

Practical Use

Practical Example

Decision Check

Ask whether Indication of Interest (IOI) changes the investor’s true exposure, return driver, liquidity, tax result, drawdown risk, or role in the portfolio.

Watch For

Investment labels are shortcuts, not substitutes for look-through holdings analysis, valuation discipline, fee and tax drag review, liquidity checks, and risk sizing.

Interpretation Note

Use Boundary
